4IMPROVEMENT IN SHlNGLEi-MACHINES.

The'shsdule referred to in these Letters Patent and making part of the same.

To-all twhom it may concern: A

Be it known that 1, CHARLES SHELMlDINn, of Summit, in the county of Schoharie :ind State of New.

York, have invented a new and improved Machine for Shaving Shingles, 85e.; and I do hereby declare that the following isa full, clear, and exact description thereof, which willl enable others skilled in the art to makev and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure 1 represents a plan or top view ot' my iinprovedmachine for shaving shingles.

My invention relates to shinglc-n1aehines5 and my object is to introduce to the public certain improvements thereon, which will first he described in connection with all that is necessary to at'nll under standing thereof, and then clearly specilied in the laim.

A in the drawing rej'n-csents' the frame ot' my improved shingle-shaving' machine.

it is made ot' metal, or other suitable material, of such suitable size and shape as to properly sustain and hold the lmachinery connected with the apparatus.

Near one end, which I will denoniinate the rear end of the trame, is hung inthe same the transverse driving-shaft B, which receives rotary motion by snit*- ahle mechanism.

The driving-shaft is provided with two cranks, a am b, standing opposite to each other, as shown in iig. 4.

lhe crank a has nearly or quite double the length ofthe crank l, and servos to iced the shingles to thc knives, while the shorter crank is used for carrying the shingles' through the cutting apparatus.

llhe feeding apparatus consists ot' two sliding frames, (i and l).

The frame C is, hy a rod, c, connected with the crank a, and is mainly below the table or platform E of the frame A.

It supports above said platform a transverse bar or'driver c7, the supportiug-arms cof' which project through slots ot' the platform E,as indicated in iig. 1.

-The shingle to 4he cut heilig placed upon the platform E in front of the driver d, is by said driver pushed forward toward the cutting apparatus.

The front 'or pushing face of the driver (l is slanting, so as to recede toward its lower part, as shown in iig. 4. 1twill thereby prevent thc rear end of the shingles from tipping or vspringing up, and will always hold the sume in the proper position.

rllhe front frame 1) rests on rails j' f, that project from the inner tacos of the cheeks or sides o t` the frame A.

The platform ll is continued hut a short distance in t'ront ot the forward position ot' the frame (i, and is not in the tin-ward part ot' the frame A.

The frame I) constitutes the i'ront, but movable, platform of the frame A.

A rod, y, connects the front frame Dwith the short crank 7).

The fra-me D carries side plates 7:, 7e, which project beyond the sides ot the frame 1\,to form movable side tables.

Each of these tables hrcontains a projecting vertical plate, i, which has two vertically-znljustahle plates, 7.2 7.", as shown in iig. 3.

The plates 7.1 7;/ serve, respectively, to support and hohl pivoted levers F F, which are grooved on their inner faces, for the purpose ot adjusting the planingknives vertically.

G and H are the two lrianingfkuives, set in inclined positions against each other, so that their cutting-edges are opposite each other, as shown in tig. 4.

Theplanes are set, respectively, in sliding trames I and J, which are vertically adj ustablc in the frame A.

rlhc upper knit'c G is Illing in the frame I, which slides in or on cars lthat project from the sides ot' the frame A.

A pin, m, proj'jccts from the frame I int-o the groove on the inner i'aces of the levers l".

lhe level' li, when swung on its pivot, will, therefore, s ervc to adjust the knife G vertically.

The lower knife, 1-1, is secured in the lower frame J, which has a pin, n, projecting into the groove oi` the lever F', so that the knife will lio-vertically adjustable by means of said lever ln the drawing l have shown a pair of levers, F l1",

n each side of the niacliine. Asingle pair will, howiver, be s ntiieient.

The levers F l"I liaii'e iiiclliied slots o at t ieir outer wiiigiiig ends.

eet from asliding elbow-lever, li.

This lever is, by a spring, lr, held against the plate to be. carried along by the saine, butstill to be inlependently adjust-able.

llhe ends of the lever L strike, during tlie,nio lion of the fraine A, respectively, against stationary stops, s andjf, that are secured to the sides of the raine A.

lhe stops s and l are. adjustable and removable.

At the end of the backward stroke of l), the lever [i will strike the back stop, s, and will tliereby'be pushed forward, to carry the pins p into the forward Jr diverging ends ot' the slots o.

Theback ends of the levers .lf' lf' will thereby be. drawn together, so that said levers will be inclined.

'lhc grooves, 'on their inner sides, will thereby also be inclined, so that they will serve, daring the ensuing forward niotion ot' the franic l), to gradually draw the knives ti lt together. lThe taper will thereby be prodnecd'on the shingle.

At the end'of the forward stroke the front end of the lever li will strike the stop I, whereby said lever will be pushed backward to swing the plates l li" apart, and spread the knives.

"lhese will .remain thus Aspread during the' backward inotion, so that they 'may be in position lbr'taking` hold of the thick endfofj the shingle.

.lust behind the kii'ivesptgvr 1iA is arranged, abore the platform lf), a vertically-adjnstable franie, 3l', ari-ying a transverse roller, n, at its4 lower end', and pressed down npon the platforni by a spring, l'.

This roller is Isnialler in the niiddle than at the ends, being thus-wil' donlile conical forni, as shown in lig.

",tlie. li'aino and roller M serve io hohl the shingle down, and to apply enough pressure. to inake ii niove steady'. n

The double inclination ol' the roller u serves to keep the shingle in the rightdireetiou; preventing it ii'oni swing to the right or left.

Upon the rear part of the inovable platform l) is arranged the self-acting clanip N, which is a plate, pivot'ed to proiecting ears 1e.

Its weight causes it. to swing backiard against a lixed plate a'.

\Vhcn the shingle presses forward, the knife-edge of the elanip N will hohl it on the platforn'i 1).

A spring-foot', t), pivoted to a projecting portion of the l'i'aiiie A, is held down upon the platforui l), and retains the shingle on the saine after the clanipX has released il.

Each of the enging-knires L l is secured to a ii'anie, n', which is supported by a transverse rail or rails, b', of the. franie A, directly in front of the knives tir li.

The, ti'anies c' are laterally adjustable, and are set by nieans of swinging levers 1l.

Each lever llis, by a pin, c', pivoted to the extreine front end of the franie A, as shown in tig. .i.

'.llie rear end of the lever It tits tlii'ongli a slotted arni, d, of the frauie c', as indicated in ligs. T and S.

rlo lthe inner side of t-lie lever lt is pivoted, near thel rear end, a spring-lever, S, which is -lield up against an inclined stop, c, by a spring, f'.

,lhc upper face of the lever S carries a wedge, g', which works in conjonction with a pin, h', projecting downward iioin the tianie or platform l).

While the platform D nieves forward, the pins h throu'fli these slots are titted pins p )i that pro-I will nieve over the wedges y', simply depressing the levers S, the wedges being thinner at the rear ends to admit the pinsh.

lhe levers lt are then thrown toward each other by powerful springs .l, so that the edging-knives are thereby thrown against tilie edges of the shingles.

When the pins h. have passed the wedges, the levers S are thrown up by the springs j".

During the backward mot-ion of the slide l), the pins h' iiiove along the oblique edges of the wedges y', and serve thereby to gradually swing the levers Brand their knives l apart, allowing them to t over the end of a new shingle.

.As soon as near the. end of the backward stroke the edgers l. have arrived in line with the new sliii1- gie, the pins 7i. pass the wedges andliberate the levers 'l S, se thabtlie knives l inay, by the springs T, be thrown against the shingles.

'lhe operation ot' the machine is as follows:

'.l`lie shingles to be shaved are successively placed upon the platforni lll in front of the driver d.

'lhe rotation ofthe shaft B will move the frame (I lorwaijd, so'lliat the. driver will pnsli the shingle ahead between 'the cutters (i H, and under the When thel crank o has iiioved the frame C as far f forward as possible, the fraaie 1) eoin'niences to move tbrward, and td is again moved back.

During the. nioiiientfary dead-point the roller 'it holds the sh'ngle iii place, and prevents its being again 'taken back by the iiiction ot' the frame G. f As soon as the ti'anie l) begins to move forward, the knives till are gradually thrown together, and shave both sides of the shingle to produce the requisite taper.

The edgers l are also thrown against the edges of thel shingle and plane the saine.

'lhe clanip X holds the shingle on the fraine 1),- aiid draws it forward with the saine.

-is soon 'as the franie l.) coninicnces again to niove backward, the shingle is released by they clainp N, but is held on Il) by the presser-foot t), which retains it until it is pushed out by the next shingle.

During the backward inotion of the traine D, the knives (l, 1l, and l, are'again spread, as aforesaid, ready for the next shingle.

For dressing stares, the knives G ll are replaced by such having, respectively, convex and' concave cutting-edges.

',lhe. stops, s and l, are renioved, and the levers .F i" held parallel, so as to keep the cutters in the saine relative position throughout the entire operation.

Lthediirer (l iiiay also be replaced by one having no 'slanting edge, and the roller u, as `well as the selfacting clainp, by one having a rounded circumference, e., larger in the middle than at theends Having thus described niy invention,
